c. 25 years1 / 25 x 1004% per year

d. 40 years1 / 40 x 1002.5% per year

e. 5 years1 / 5 x 10020% per year

f. 4 years         1 / 4 x 10025% per year

g. 20 years1 / 20 x 1005% per year

Step-by-step explanation:

Under straight line method of depreciation, equal amount of the depreciation is reduced throughout the useful life of the asset. Using the following formula:

Straight line depreciation rate = 1 / Useful Life x 100

So:

a.10 years1 / 10 x 10010% per year

b. 8 years1 / 8 x 10012.5% per year

c. 25 years1 / 25 x 1004% per year

d. 40 years1 / 40 x 1002.5% per year

e. 5 years1 / 5 x 10020% per year

f. 4 years         1 / 4 x 10025% per year

g. 20 years1 / 20 x 1005% per year
